Abstract

LA INVENCION TIENE POR OBJETO Y REVESTIMIENTO AISLANTE PARA LA PROTECCION TERMICA DE CUERPOS REFRACTARIOS EN METERIALES CERALICOS QUE SIRVEN PARA EL COLADO CONTINUO DEL ACERO Y DE OTROS METALES. EL REVESTIMIENTO ES UNA SUSPENSION QUE COMPRENDE, PREFERNETEMENTE EN PESO: 30 A 85% DE GRANOS DE SILICE VITROSA, 0 A 10% DE FIBRAS CERAMICAS, 0 A 7% DE LIGANTE, 0 A 4% DE FRITO Y DE 15 A 30% DE AGUA, DESPUES APLICACION DE UN ANTIOXIDANTE EL CUERPO REFRACTARIO (TEMPERARATURA AMBIENTE O PRECALENTADA) EN UNA COMPOSICION DURANTE UN PERIODO REGULADO DE 5 A 60 SEGUNDOS PARA OBTENER UN REVESTIMIENTO DE 1 A 6 MM DE ESPESOR, EL CUERPO REVESTIDO SE SECA. SE PUEDEN UTILIZAR LOS REVESTIMIENTOS PARA EL DERRAMADO EN FRIO DE UNA COLADA CONTINUA SIN EXIGIR PRECALENTADO.
